COLMONOY No. 70 and No. 72 contain high tungsten which hardens the matrix and provides superior hard-facing materials. No. 70 hasexcellent resistance to fretting corrosion. No. 72 is harder than No. 70 and provides better resistance to low-stress abrasion and is well suited to resist scouring actions. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on high temperature performance as well as forming, heat treating, machining, joining, and powder metal forms. Filing Code: Ni-210. Producer or source: Wall Colmonoy Corporation.
